CARBURETED FUEL SYSTEM

Only the 5.7L engine is equipped with a carburetor. Two 4-bbl. carburetors were offered, the M4ME and M4MEF. The difference between the two models is that the M4MEF has a wide open throttle mixture control. The M4ME was used only on some 1987 models. The M4MEF was used for 1988-90 models.
